' Application filed November 11, 190i; Serial No. 81,845. (N model.)

To all whom, it may concern:

Beit known that we,CHARLEs H. LoEw and LEONARD BOLZ, citizens of theUnited States, residing at Cleveland, in the county of Guyahoga andState of Ohio, have invented certain new and useful Improvements inMachines for Washing Filtering Material; and we do declare that thefollowing'is afull, clear, and

exact description of the invention,which will toenable others skilledinthe art to which it appertains to make and use the same.

This invention relates to a machine for washing'filtering material, suchas cellulose, wood-pulp, and the like; and the object of the inventionis to furnish a machine which will thoroughlycleanse filtering materialafterithas become fouled in filteringbeer,'w.ine, and otherliquids, thuspreserving the said materialto be used over again and again instead ofthrowing it away after being used the first time. 1

, In the accompanying drawings, Figure-l is an end elevation of themachinelooking in from the right of Fig. 5. Fig. 2 is a cross section ona line corresponding to line 2 .2, Fig. 5. Fig. 3 is a plan View of thedischarge end of the perforated separating-cylinder at the top of themachine. Fig. 4is an enlarged view of the inner portion ofone of thewatero inlet pipes. Fig. 5is a longitudinal sectional elevation ofth'emachineon line was, Fig. 2. Fig. 6 is a horizontal sectional plan viewon line corresponding to y y, Fig. 2.

A represents a suitable washing-tank sup- Q 4 5 controls the saidoutlet, and this or any equivalent medium may be used for opening andclosing the said outlet.

, Two means of agitation within tank A are used, but chiefly the twosets or pairs of propeller blades or wheels D. These are fixed gwith thepower.

1 upon shaft E and set thereon to throw from the center of the tanktoward its ends, thus tending to produce vacuum at said center andcausing the materialto flow thereto from both ends afterit has beendrawn from the .55

center and' thrown. toward the ends. The shaft E'is connected up in anysuitable way The other source or means of agitation is the inflowingwater through the two inlet-pipes G, entering at one side of the tankabout midway its elevation in this instance, and having heads 4:,constructed with .slots 5 in their bottom. The water entering throughthese slots is caused to spread as it descends, so as to strike thecurved side of the tank with a sweeping effect, thus counteracting thetendency of the material to cling to the side and bottom of the tank.

At the'top of the tank there is a revolving screened cylinder H,occupying the entire length of the tank and forming the outlet ordischarge duct for the water. To this end the said-cylinder is supportedon a shaft 72., adapted to be rotated by power and resting in suitablebearings at its ends, and has a somewhat-contracted discharge-neck '7,which projects outward beyond the casing or tank A i and empties intothe receptacle-mouth 8 for overflow or discharge pipe 9. A gasket 10serves to make a fairly close connection below neck '1 to preventbackflow of water.

Cylinder H is a perforated body and is further covered with wire-gauze11 of such closeness of mesh that the filtering material will beheldback, while the fouled water is caused to flow out or overflow throughsaid cylinder, and the rotation of the cylinder in the water keeps itclean. Thus a large volume of water may be kept on the flow or runthrough the tank, and the construction-and arrangement of the parts issuch that the cleansing effect is especially promoted thereby. Thus itwill be observed that cylinder H is located over the inlet-pipes Grather than over the center of the tank, and the mixers are caused toro- 5 tate with a sweep toward said cylinder, which itself rotates inthe same direction as the mixers, and thus facilitates the movement ofthe water up on that side of the cylinder beneath its hood 12 ratherthan throwing itin theoprco posite direction against the inward sweep ofthe water through pipes G and into the corner of the tank above. Thiswould simply clog the machine and defeat its operations.

Suitable valves l-t control the inflow of water through pipes G, and hotand cold water can be used, or either, as the material to be cleansedmay require.

The top of the tank has a compound cover, the whole being capable oflifting together on hinges 15, or the front part 16 may be turned aloneon hinges 17 on the front edge of the rear section or hood 1? forcylinder H.

In the operation as above described, with the flow from the agitatorsinto the space behind cylinder I-I there is a tendency for the materialto pack behind said cylinder, and I have therefore provided the cylinderwith a longitudinally-placed blade 20 on its periphery to carry thematerial downward and throw it into the channels of agitation fromblades 0 and D.

What we claim is'- The tank and the agitator therein, in combinationwith a perforated cylinder arranged across the top of the tank anddipping into the same its full length, a shaft h supporting saidcylinder and bearings therefor in the tank atone end and a lateralextension 8 fixed to the tank providing a bearing at the other end, saidextension having an outlet 9 at its bottom, and a discharge-neck 7 onthe end of cylinder H projecting across the casing A into extension 8, ascreen covering 11 over said cylinder and means to rotate thecylinder,sub stantially as shown.

Witness our hands to the foregoing specification this 23d day ofOctober, 1901.
